This invention relates to v(lirigible headlights designed for use onmotor vehicles, the primary object of the invention being to. provide alamp construction wherein the pathof travel of the motor vehicle will beadequately illuminated, when the-vehicle is making aturn. 1

,An important object of the. invention is to provide a device ofth'ischaracter wherein the usual complicated dirigible headlight structuresare simplified, the operating levers and mechanism being reduced to theminimum. v

A still further object. of the invention is to provide a device of thischaracter which will operate automatically and electrically,

a novel arrangement being provided whereby solenoids act as the meansfor moving the lamp post. 7

lVith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawings:

Figure 1 is aside elevational view illust-rat-ing a lamp and operatingmechanism constructed in accordance with the invention.

Figure 2 is a longitudinal sectional view through the solenoid forming apart of the invention.

F igure3 is a front elevational view of the solenoid and lamp.

Figure 4 is a diagrammatic view illustrating the circuits leading to theelements of the solenoid.

Referring to the drawings in detail, the reference character 5 indicatesan elongated casing in which the solenoid forming a part of theinvention is mounted.

The solenoid includes a plurality of in dependent coils 6 as shown byFigure 2 of the drawings, which coils are in circuit with a suitablesource of electric supply through the wires 7 the-ground wire 7 beingcon nected with the contact plate 8, as clearly shown by Figure 4 of thedrawings.

As shown more clearly by Figure 2 of the drawings, the tubular casing 5is provided with openings to receive a lamp post designed to accommodatethe segment 8 which is provided with teeth 9 designed to cooperate withthe teeth 10 formed along one edge ofthe bar 11 of the yoke 11 whichyoke has bars 12 extending from its ends that support armatures 12 ofthe solenoids.

The lamp postis indicated by the reference character 13 and is supportedin suitable bearings 14 to permit the lamp to be moved with the minimumamount of power; This lamp post 13 extends through the yoke and supportsthe segment 8 so that move ment of the segment will produce a relativemovement of the post and lamp 15 supported at the upper end of the post13.

The wires 7, while they have connection with the coils of the solenoid,they are connected with contact points 16 of the switch 17 that issupported on the steering column adjacent tothe front axles' of themotor vehicle. The reference character 18 indicates a switch arm whichmay be supported on the steering post in any suitable manner to causethe same to move over the contact points 16, with the turning of thefront wheels of the vehicle.

From the foregoing it will be seen that when the front wheels of thevehicle are moved, the switch arm 18 is moved to complete a circuit tocertain coils of the magnet, the armature adjacent to the coilenergized, will be drawn to a'position within the energized coil, movingthe yoke 11 to cause the segment 8, lamp post 13 and lamp 15 supportedat the upper end thereof, to move correspondingly to illuminate the pathof travel of the vehicle equipped with the device.

Closing the ends of the casing 5 are caps 5 that are provided-withopenings 6 to release the air in the ends of the casing when the cores12 move therethrough regulating the speed of the movement of the cores.

VVhe'n the vehicle wheels are moved to their normal or straightpositions, the switch arm 18 will be moved to a position as shown byFigure 1 and the post 13 returned to its initial position due to thefact that the switch arm 18 must pass over the contact points of theswitch in its return movement to its initial position.

It might be further stated that it is further contemplated to employ asuitable switch mechanism to be positioned adjacent in; p

ill

to the operators seat so that the switch mechanism may be manuallycontrolled for operating the headlight.

I claim:

1. In a device of the character described, a solenoid including acasing, a plurality of independent coils arranged within the casing, ayoke having armatures extending from its ends, said armatures operatingwithin the coils, a lamp post having a lamp at its upper end mounted forrotary movement in a horizontal plane, means for transmitting movementof the rod to the lamp post, a switch member having; contact points,wires leading from the contact points to the coils, a switch arm adaptedto complete circuits between the contact. points to energize certaincoils of the magnet to move the armatures and rod to operate the lampsupporting post and lamp.

2. In a device of the character described, a tubular casing, solenoidsat the ends of the casing, each solenoid including a plurality ofindependent coils, armatnres operating within the coils and adapted tobe magnetized. by the coils, a switch member and electric circuitleading to the coils, means for operatin; the switch member to energizecertain coils to more the armatnres certain distances, lamp supportingposts, and means for transmittinp movement of the armatures to the lampsupporting posts.

3. In a device of the character described,

a tubular casing, a solenoid arranged in each s CHAS. A. MCGRAY.
